SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill helps identify and mitigate timing side-channel vulnerabilities in cryptographic code, which can otherwise lead to the leakage of sensitive information like private keys.

Core Features & Use Cases

Timing Leak Detection: Uses statistical analysis (dudect) and dynamic tracing (timecop) to find execution time differences correlated with secret data.
Root Cause Analysis: Pinpoints the exact lines of code responsible for timing vulnerabilities.
Use Case: When auditing a new cryptographic library, use this Skill to run dudect to statistically detect any timing anomalies, then employ timecop to pinpoint the specific conditional branches or memory accesses causing the leaks.

Quick Start

Use the constant-time-testing skill to audit the provided C code for timing vulnerabilities.

FAQPage Schema

How do I detect timing side-channel vulnerabilities in cryptographic code?▼

Timing side-channel vulnerabilities are detected by applying statistical analysis with dudect and dynamic tracing with timecop to measure execution times and trace secret data flow in cryptographic implementations.

What is the best way to audit a cryptographic library for timing leaks?▼

Auditing cryptographic libraries for timing leaks requires running dudect to statistically detect execution time anomalies, then using timecop to pinpoint specific conditional branches or memory accesses causing the vulnerabilities.

Why does my cryptographic implementation leak private keys through timing attacks?▼

Cryptographic implementations leak private keys through timing attacks when execution time differences correlate with secret data. Root cause analysis pinpoints exact lines of code responsible for timing vulnerabilities.

Can I use dudect and timecop together to find conditional branches causing timing leaks?▼

Yes, dudect and timecop work together to detect timing vulnerabilities. dudect statistically measures execution time anomalies while timecop dynamically traces secret data flow to pinpoint leaking conditional branches.

How do I ensure constant-time execution for sensitive security operations?▼

Constant-time execution for sensitive operations is ensured by auditing security-critical code to detect timing side-channel vulnerabilities, ensuring execution times do not correlate with secret data like private keys.

Do I need C code to audit for timing vulnerabilities with constant-time testing?▼

Auditing for timing vulnerabilities typically applies to C code in security-critical implementations. The skill analyzes cryptographic primitives to ensure constant-time execution for sensitive operations.
